METAL CONTAINER.

Application filed. June 13, 1919.

Cleveland, in the. county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in and Relating to Metal Containers, of which the following is a specification.

This invention relates to containers (sometimes called drums or barrels) formed of metal, such as iron, steel or other metals.

One object of the invention is to provide improved means for protecting or reinforcing the chime or chimes of the container toinsure ample protection thereof against damage to or leakage of the chime or j oint due to the use or handling of the container.

Another object of the invention is to provide the chime of the container with an armoring ring and to secure such ring to the chime in a novel manner to prevent displacement thereof' by vthe rough usage to which the container may be subjected.

Another object of the invention is to provide a container with a chime and a reinforcing ring which are so shaped and constructed that the ring when applied to the chime will automatically be locked thereon against displacement due t'o usage to which the container may be subjected under ordinary conditions.

A further object of the invention is to provide an improved reinforced chime for a container the armoring or protecting ring of which is sha-pcd and arranged to expose the lower part or portion of the chime, whereby suitable repairs can be readily made in case of leakage at the chime.

Other objects of the invention will be apparent to those skilled in the art to which my invention relates.

For the purpose of illustration, I have, in the accompanying drawing shown and herein described one form of container embodying my invention.

Fig. 1 is a fragmentary vertical section of a container embodying my invention.

Fig. 2 is a. fragmentary section of the chime protecting or armoring ring.

Fig. 3 is an enlarged section of the chime after it is completed, but before the armoring ring is applied.

Serial No. 303,996.

Fig. 4 is an enlarged section of the chime after the ring is applied.

Fig. 5 1s a fragmentary sectional view of the ring, enlarged.

In the drawing, 1 indicates as an entirety `the container formed-of sheet metal, such as iron or steel. The container may be of any desired size and shape and its sides may be straight or bilged. la indicates the body :or shell of the container the longitudinal edges of which are preferably welded together. Only one end ofthe container is shown. As' both ends of the container are preferably formed in the same way, the following description of one end or the chime and reinforcement thereof will suffice for both. ends heads of the container.

2 indicates as an entirety the head of the containerl formed of sheet metal such as iron or steel. The head is preferably provided with an annular side wall which fits within the body or shell la, in a well known manner. 3 indicates as an entirety the chime, which is preferably formed by bending over the free edge of the body la, as shown at 3a, then folding around said flange the metal of the flange 2a provided on the head 2 to form what is known as a double seam oint, clearly shown in Figs. l and 3. The folds of the. flanges 3a and 2a are preferablyarranged exteriorly on the container.

5 indicates an angular groove or recess formed in .the exposed face or wall of the folded over flanges 3a, 2a, and substantially midwaybetween the upper and lower ends of the joint or chime. IVXThe groove 5 is preferably formed by hand or pressure rolls, the ell'ect of which. is to press inwardly the folds of metal, as clearly shown in Figs. l, 3, and 4. I preferably form the groove at the time the folds of metal are compressed or flattened face to face, the flattening roll being suitably shaped for this purpose. This operation not only serves to form the groove 5, but provides a shoulder 5El the purpose of which will be later set forth.

6 indicates as an entirety the armoring ring which reinforces the chime and protects it against damage due to the rough usage to which the container may be subjected. The ring 6 preferably has a side wall 6a, adapted to extend downwardly and snugly lit the side wall ofthe head 2. 6h indicates the flange of the ring which is shaped to fit over and in substantially snug engagement with the upper and outer surfaces of the chime and around the shoulder 5 with its free end, indicated at 6, extending inwardly into the groove 5. The ring is preferably formed from a band of metal and shaped as shown in Figs. 2 and 3 by a suitable die or a rolling operation, after which it is positioned on or over .the chime by pressure or a hammering operation, the elasticity of the metal permitting the free end of the ring flange 6 to slide over the Shoulder 5a into the groove 5. When the ring is formed in this manner` I prefer to make the flange 6b slightly larger than thechime in order to form a recess between its inner surface and the surface of the chime. This construction insures that the free end 6c of the flange will extend into and engage the bottom of the groove 5. By this arrangement and construction the ring 6 is clamped to the chimein a ysecure manner which (l) prevents its displacement due to the rough and severe usage to which the container may be subjected when in use either in a filled or unfilled condition, and (2) strengthens and amply protects the chime or joint against breakage or damage.

By providing the chime joint with an annular groove a relatively tight joint is provided, especially as the folds of the joint are interlocked, one with another, thereby insuring a leakproof joint. Furvthermore, by providing the joint with the annular groove, the flange of the reinforcing ring can be readily positioned against displacement wi-thout undue pressure upon the metal constituting the joint; at the same time the reinforcing ring protects the joint and maintainsthe folds of the metal against unfolding, either due to (l) shocks and jars incident to thel rough usage of the container or (2) internal pressure of the contents of the barrel. Furthermore, by extending the ring downwardly.- parallel to and snugly against the side w'allof the head 2, the latter is rigidly maintained in position and prevented from expanding outwardly.

The above described construction of joint or chime and reinforcement therefor is advantageous for the'reason that it provides a relatively simple form of reinforcement for the chimes of containers, drums and barrels.

Due to the high cost of materials and labor, as Well as the great expense incident to shipment ofheavy containers a demand has been created for relatively light, inexpensive containers which are constructed for rough and repeated use or shipment. By my invention I am able to construct containers of relatively light material and to reinforce chimes thereof to amply protect and strengthen them-against damage so that the containersjcan be 'used and reused or reshipped many times.

My invention has the further advantage of exposing the chime joint. As clearly shown in the drawings the flange 6" of the ring 6 extends around and down upon the chime joint approximately one-half the distance; this leaves the lower end or portion of the joint freely exposed entirely around the container so that repairs can be readily made in the case of leakage.

While a container constructed according to my invention as above set forth may be vention will suggest themselves, without de-` parting from the spirit and scope thereof. My disclosures and description herein are purely illustrative and are not intended to be in" any Sense limiting.

What I claim is r- 1. AI receptacle provided with a chime or joint formed by folding together the flanges of the body and head of said receptacle, said chime or joint being formed with a groove or channel in its outer side wall, in combination with a ring having a body section and a flange rolled backwardly to provide a downwardly and inwardly extending circumferential free edge, said ring being adapted to be slid on and over` said chime or joint to position the body section against the inner Wall of said chime or joint and the inwardly extending circumferential free edge of the flange in the groove or channel thereof. p

2. A receptacle provided with a chime formed by folding together the flanges of the body and head of said receptacle, said folds of the metal flanges being ressed inwardly between their upper and Iower ends to interlock their abutting faces together and form a groove around the chime below its free circumferential edge, and a ring having a flange bent downwardly and inwardly and arranged to be sprung over the free edge of said chime to position the circumferential free edge of the ring flange in the groove formed in said chime.

3. A receptacle comprising a flanged body and a head having a vertical side Wall litting within the body and a flange, said flanges being folded together to form a chime or joint, and the outermost folds of 'the flanges being pressed inwardly between their upper and lower edges to form a groove or channel around the outer side surface of the chime or joint, and siv ring arranged to slid-ably fit the inner vertical side wall of the head and provided with a flange extending downwardly and inwardly, Whereby it may tit over the free edge of t-he chime or joint and its circumferential free edge to be disposed in ,the groove or Channel to lock 10 the ring in position on said chime or joint. In testimony whereof I ulix my signature.
